I'm planning to do so... Recently I have added C.bicolor, C.acanthops and Pomacanthus navarcus in to my tank, and there already was a C.bisbinosus. No problems... Bicolor was the same size, acanthops a bit smaller and the navarcus a bit bigger than the bisbinosus I have. They all get along nicely...
Now I'm gonna throw in the C.potteri and maybe even C.loricula.
Have to see what happens then...
